Hackers are targeting senior managers of large firms - along with members of their families - in a new wave of highly-focused email attacks. On 26 June, net security services firm MessageLabs intercepted more than 500 individual email attacks targeted against individuals in senior management positions. The attack email often featured the name and job title of the intended victim in their subject lines. Chief investment officers accounted for 30 per cent of the attacks, 11 per cent were directed against chief executives.

Other job titles among the top 10 targets included chief information officers, chief financial officers, directors of research, directors of development, and company presidents.
